函数名称：moyo_envp - Check envp[] in "struct linux_binbrm".*@env_name: The name of environment variable.*@env_value: The value of environment variable.*@envc: Length of @envp.*@envp: Pointer to "struct tomoyo_envp".

函数原型：static bool tomoyo_envp(const char *env_name, const char *env_value, const int envc, const struct tomoyo_envp *envp, u8 *checked)

返回类型：bool

参数：

类型参数名称
const char *env_name
const char *env_value
const intenvc
const struct tomoyo_envp *envp
u8 *checked
68  name等于env_name
69  tomoyo_fill_path_info( & name)
70  name等于env_value
71  tomoyo_fill_path_info( & value)
72  以i小于envc循环
75  如果非moyo_path_matches_pattern - Check whether the given filename matches the given pattern.*@filename: The filename to check.*@pattern: The pattern to compare.* Returns true if matches, false otherwise.* The following patterns are available.* \\ \ itself.则继续下一循环
77  checked等于1
78  如果value则
79  result等于moyo_path_matches_pattern - Check whether the given filename matches the given pattern.*@filename: The filename to check.*@pattern: The pattern to compare.* Returns true if matches, false otherwise.* The following patterns are available.* \\ \ itself.
81  如果is_not则result等于非result
83  否则
84  result = true
85  如果非is_not则result等于非result
88  如果非result则返回:false
91  返回:true
